New Target for Uveitis Therapy

To explore the role of the cGAS–STING pathway in uveitis and its potential as a therapeutic target.

cGAS–STING pathway is strongly activated in inflamed retinas.
Mitochondrial DNA accumulates in the cytoplasm post-LPS exposure, triggering cGAS activation.
Cgas knockout mice showed significantly reduced ocular inflammation compared to wild-type mice.
Absence of cGAS led to decreased retinal macrophage recruitment and increased regulatory T cells.

The cGAS–STING pathway is a central driver of inflammation in uveitis, suggesting it could be a novel therapeutic target.

Further validation in human tissues is needed.
Uncertainty whether STING-dependent mechanisms are solely responsible for the observed effects.

Targeting the cGAS–STING pathway may provide a new strategy for treating refractory uveitis, pending further research.
